In a popular Internet role-playing game called Second Life, people can create a virtual identity for themselves, choosing such things as their age, sex, and appearance. These virtual characters then do things that people in the real world do, such as having sex. Depending on your preferences, you can have sex with someone who is older or younger than you â€“ perhaps much older or younger. In fact, if your virtual character is an adult, you can have sex with a virtual character who is a child.
